Final Results of the MAJORANA DEMONSTRATOR's Search for Double-Beta Decay of $^{76}$ Ge to Excited States of $^{76}$ Se

I. J. Arnquist, F. T. Avignone, A. S. Barabash +45

$^{76}$ Ge can $I^^{2} I^^{2}$ decay into three possible excited states of $^{76}$ Se, with the emission of two or, if the neutrino is Majorana, zero neutrinos. None of these six transitions…

Low-energy neutrino responses for 71Ga by electron capture rates, charge exchange reactions and shell model calculations

Yoritaka Iwata, Hiroyasu Ejiri, Shahariar Sarkar

Weak Gamow-Teller (GT) responses for low-lying states in $^{71} Ga$ are crucial for studying low-energy solar neutrinos and the Ga anomaly, i.e., the possible transition…

Right-handed weak currents in neutrinoless $I^^{2} I^^{2}$ decays and ton scale $I^^{2} I^^{2}$ detectors

H. Ejiri, T. Fukuyama, T. Sato

Right handed weak-currents (RHCs) in the left-right (L-R) symmetric model for neutrinoless double beta decays (DBDs) of both the $0^{+} \to 0^{+}$ and $0^{+} \to 2^{+}$ transitions are dis…
